A scientist wrote down the steps to perform a chemical experiment, but they are out of order. Help the scientist by rearranging
his steps in the correct order. Measure out 0.3 grams each of the solids, lead nitrate and potassium iodide. Watch mixture change from clear to a yellow solid and record observations. 1 Measure 100 ml distilled water into each of two beakers. 1 Write a science report detailing results and conclusions. Dissolve each solid in a separate beaker of water. Pour both solutions into one container and slowly stir. Create a presentation and share findings with peers. Predict what happens when lead nitrate reacts with potassium iodide.

Answer and Explanation:
For the following balanced reaction:
PCl₅(g) ↔ PCl₃(g) + Cl₂(g)
We can see that all reactants and products are gases, so it is an homogeneous equilibrium. The expression for the equilibrium constant Kp can be written from the partial pressures (P) of reactants and products as follows:
Where PPCl₃ is the partial pressure of PCl₃ (reactant), PCl₂ is the partial pressure of Cl₂ (reactant) and PPCl₅ is the partial pressure of PCl₅ (product).
